Passenger Compartment Heating Resistor Management (Mégane II only):
In order to reduce the time required to heat up the passenger compartment, the vehicle is fitted with Passenger
Compartment Heating resistors (RCH). These passenger compartment heating resistors are run and controlled by
the UCH. The injection computer authorises or prohibits the operation of the passenger compartment heating
resistors according to the operating phases and engine power needs.
Cruise control/speed limiter management:
The vehicle cruise control function, when activated, allows you to keep the vehicle speed at a selected value
regardless of the driving conditions encountered.
Using the control buttons, the driver can increase or reduce the speed of the vehicle.
If the driver wishes to exceed the cruising speed, he may:
– depress the accelerator pedal and exceed the cruising speed (the vehicle will return to the initial cruising speed
once the driver takes his foot off the pedal),
– press the system control buttons.
The cruise control function can be deselected either by:
– the system control buttons,
– deactivating the cruise control switch,
– when system events are detected, such as the brake pedal or clutch being depressed,
– when system errors are detected such as an inconsistent vehicle speed.
The cruise function can also be temporarily disabled when the driver wants to increase speed by depressing the
accelerator pedal. The cruising speed is resumed when the driver releases the accelerator pedal.
The vehicle will then attempt to reach the cruising speed at a controlled acceleration rate.
It is possible to reactivate the vehicle speed control and resume the last cruising speed after deactivation (computer
supply not cut off).
When activated (using the selection switch) the vehicle speed limiter function limits the vehicle speed to
a preselected value. The driver controls the vehicle in the normal way using the accelerator pedal until the limit
speed is reached.
If an attempt is made to exceed this speed, the system ignores the pedal request and controls the vehicle speed in
the same way as the cruise control function, provided that the driver keeps the accelerator pedal sufficiently
depressed.
As with the cruise control function, the cruising speed can be altered using the control buttons by pressing briefly or
keeping the switch pressed.
For safety reasons, the limit speed can be exceeded by depressing the accelerator pedal beyond the pedal position
limit value. The vehicle speed is then totally controlled as a function of pedal position until the speed falls back below
the cruising speed when the speed limiter function will once again be reactivated.
If the driver wishes to exceed the cruising speed, he may:
– exceed the accelerator pedal's kickdown point,
– increase the limit speed by pressing or pressing and holding the limit speed switch.
The speed limiter function can be deselected either:
– the system control buttons,
– by switching off the speed limiter switch,
– when system events are detected, such as the brake pedal or clutch being depressed,
– when system errors are detected such as an inconsistent vehicle speed.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the engine is started or following a road test.
Special notes:
The cruise control/speed limiter function is inhibited.
Use bornier Elé.1681 or Elé.1590 for any operation on the injection computer
connectors.
WARNING
This fault may appear if the wiring harness has been damaged.
Follow the procedure described in the Wiring Check in the Introduction.
This check enables the condition and the conformity of the engine wiring harness to be checked.
If the fault is present, refer to the interpretation of the following statuses:
– ET042 Cruise control/speed limiter.
– ET415 Deactivation of cruise control/speed limiter.
Check that by pressing the buttons the statuses change and that, with the ignition switched on, all the values are
correct.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

ET042
CRUISE CONTROL/SPEED LIMITER
STATUS DEFINITIONNOT DETECTED: This status indicates that the cruise control or speed limiter function
is not present on the vehicle.
INACTIVE: This status indicates that the cruise control/speed limiter main On/Off
switch is in the rest (or neutral) position.
LIMITER: This status indicates that the driver has used the main switch to select the
speed limiter.
CRUISE CONTROL: This status indicates that the driver has used the main switch to
select the cruise control.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
NOT DETECTED
If the vehicle does not have cruise control or speed limiter function buttons, status
ET042 is permanently NOT DETECTED. This confirms that the cruise control/speed
limiter function is not present on the vehicle.
If the vehicle is fitted with cruise control or speed limiter function buttons, the main
switch is in the rest (or neutral) position and the injection computer has just been
programmed or reprogrammed, then status ET042 is NOT DETECTED.
To activate the cruise control or speed limiter function, press the main switch in the
cruise control position and then in the speed limiter position.
Return to rest position
The tool displays status ET042 INACTIVE.
If not, several steps must be checked:
1. Return to the multiplex network test page on the Clip application. Repeat the
multiplex network test. Re-establish dialogue with the injection computer. Check
status ET042. If ET042 is INACTIVE, the injection computer has detected the various
positions of the main switch. The cruise control/speed limiter is activated.
2. If ET042 is NOT DETECTED, check that the vehicle's owner has not had the cruise
control/speed limiter function disabled in the past. Contact the Techline.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

ET415
CONTINUED 1
STATUS 3
Clutch pedal depressed
Manual gearbox ONLY
The cruise control function is deactivated when the gearbox is not coupled to the engine
(clutch pedal depressed).
Status ET415 becomes STATUS 3 when driving with cruise control active (ET042
Cruise control/speed limiter: CRUISE CONTROL) and the clutch pedal is depressed.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ007
"Fault memory".
If status ET415 becomes STATUS 3 without the clutch pedal being depressed, consult
the interpretation of status ET405: "Clutch pedal".
If the vehicle is fitted with automatic transmission:
Carry out a multiplex network test, check the configuration of the multiplex network
according to the vehicle's technical definition and, in particular, the automatic gearbox
computer configuration (see 88B, Multiplex).
STATUS 4Cancel button pressed
The cruise control/speed limiter function is deactivated each time the suspend button is
pressed.
Status ET415 becomes STATUS 4, when driving when:
– Either the cruise control is active, or
– the speed limiter is active
– and the driver presses the 0 button.
This action deactivates the Cruise control/Speed limiter.
Reinitialise status ET415 on the injection computer by running command RZ007
"Fault memory".
If status ET415 becomes STATUS 4 without pressing the 0 button, refer to the
interpretation of status ET703 Cruise control/speed limiter buttons and test the R/0
control button located on the right-hand side of the steering wheel.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

STATUS 5
Cruise control or speed limiter monitoring
This status appears when the vehicle brakes or decelerates sharply without the
injection computer receiving a signal indicating that the brake pedal switch has been
pressed.
If status ET415 is STATUS 5, refer to the interpretation of:
– of status ET042 Cruise control/speed limiter,
– of status ET703 Cruise control/speed limiter buttons,
– of status ET704 Brake contact no. 1,
– and status ET705 Brake contact No 2,
to test the cruise control/speed limiter system components and find the defective
component.
Also check the operation of the accelerator pedal, and check for any faults on the
diagnostic tool relating to this component. Deal with them if necessary.
Reinitialise status ET415 on the injection computer by running command RZ007
"Fault memory".
If status ET415 changes to "STATUS 5", deal with present faults or those stored in the
injection computer.
If the fault is still present, contact Techline.
STATUS 6Gear lever in neutral (manual gearbox) or the neutral position (automatic
gearbox)
Status ET415 becomes STATUS 6 when driving with cruise control active (ET042
"Cruise control/speed limiter": CRUISE CONTROL) and:
– If the driver puts the gear lever in neutral position on a manual gearbox without
declutching or,
– if the gear lever is in neutral on an automatic gearbox.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ007
"Fault memory".
If status ET415 becomes STATUS 6 without shifting the gear lever into neutral on a
manual gearbox without declutching, or into neutral on an automatic transmission, test
the ABS computer and check the configuration of the tyre size stored in the computer. If
the configuration is correct, contact the Techline.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
